Win7 not genuine after removed dual-boot Vista

I had a dual boot machine with Vista and Win 7 Ultimate. Each installed on the same hard drive in separate partitions.

Goal was to remove Vista and add the space to Win 7.

I used EasyBCD to remove the boot entry to Vista and changed the setting to boot directly into Win 7.

That was successful.

I then used GParted to remove the Vista partition and add the space to Win 7.

That was successful.

I then started the machine with my Win 7 installation disk to repair the (I thought) the boot record.

I think that this was successful also.

After entering my login name and password for my home domain (that appears on the screen) the 'Preparing Your Desktop' message stays up for a long time and then instead of my desktop I get a blue screen with the "Windows 7 Build 7601 The Copy of Windows is Not Genuine" in the lower right corner. I hope that it's genuine since I got it direct from Microsoft.
